How to tell him I'd like to go on a date, as opposed to doing a group-ish activity together?

I've been dating this guy for a couple of months now. We haven't gone on an 'actual' date in a few weeks tho. We took a hip-hop dance class 3 weeks ago (he payed for it) and took that class again the next week (this time I payed for myself). Last week he was out of town, so we weren't able to go. I haven't seen him since the last time we went dancing and haven't talked to him much for the last week and a half. I'm pretty sure he'll want to do it this week too (it's Mon now; the class is on Thur), but I want to tell him that I'd like to maybe go to the beach and have a little bonfire or something more intimate instead. How do I tell him that? Can you give some specific examples pleaseee! Thanks :)
